Laser Welding for Commercial Vehicle Drive Axles
The use of laser welding means that the drive
ring and differential case become an extremly
stiff unit, thus eliminating fretting and allowing
a higher torque capacity. This also ensures that
the gears are able to mesh better, resulting in a
30% increase in durability, which was proven on
dynamometer tests and �eld trials.
In the predecessor generation the external ring
gear, the differential case, the pinion housing to
the carrier casting and the axle housing were
joined by a total of 36 screws.
Elimination of the screws made it possible to
optimise the �ange of one half of the differential
case as well as to remove the ribs in order to
achieve a �at surface. This resulted in a
reduction in �ow resistance and turbulence in
the transmission and therefore in fewer losses
due to oil splashing.

The using of laser welding enables the axle carrier now to
be 13kg lighter than the predecessor design and to have
smaller assembly dimensions.
The lower weight, especially of the rotating parts,
results in substantial reductions of fuel consumption.
